DCMA: A Label Switching MAC for efficient packet forwarding in multi-hop wireless networks Arup Acharya Sachin Ganu Archan Misra IBM T.J.Watson Research WINLAB, Rutgers University, IBM T.J.Watson Research Center, Hawthorne, NY Piscataway, NJ 08854 Center, Hawthorne, NY Abstract This paper addresses the problem of efficient packet forwarding in a multi-hop, wireless “mesh” network. We first explain how the packet forwarding operation in the wireless broadcast medium differs from that of a router in wired network, which typically switches packets across multiple network interfaces.
